/**
 * The container for the SOAP-specific portion of a {@code SOAPMessage}
 * object. All messages are required to have a SOAP part, so when a
 * {@code SOAPMessage} object is created, it will automatically
 * have a {@code SOAPPart} object.
 * <P>
 * A {@code SOAPPart} object is a MIME part and has the MIME headers
 * Content-Id, Content-Location, and Content-Type.  Because the value of
 * Content-Type must be "text/xml", a {@code SOAPPart} object automatically
 * has a MIME header of Content-Type with its value set to "text/xml".
 * The value must be "text/xml" because content in the SOAP part of a
 * message must be in XML format.  Content that is not of type "text/xml"
 * must be in an {@code AttachmentPart} object rather than in the
 * {@code SOAPPart} object.
 * <P>
 * When a message is sent, its SOAP part must have the MIME header Content-Type
 * set to "text/xml". Or, from the other perspective, the SOAP part of any
 * message that is received must have the MIME header Content-Type with a
 * value of "text/xml".
 * <P>
 * A client can access the {@code SOAPPart} object of a
 * {@code SOAPMessage} object by
 * calling the method {@code SOAPMessage.getSOAPPart}. The
 * following  line of code, in which {@code message} is a
 * {@code SOAPMessage} object, retrieves the SOAP part of a message.
 * <pre>{@code
 *   SOAPPart soapPart = message.getSOAPPart();
 * }</pre>
 * <P>
 * A {@code SOAPPart} object contains a {@code SOAPEnvelope} object,
 * which in turn contains a {@code SOAPBody} object and a
 * {@code SOAPHeader} object.
 * The {@code SOAPPart} method {@code getEnvelope} can be used
 * to retrieve the {@code SOAPEnvelope} object.
